1. See section 1.2 for a list of signals synchronous and asynchronous to PCLKIN.
2. See Figures 1 and 2.
3. Latency is defined as the number of clock cycles between the time when the data is latched into the device and when the
corresponding output data is clocked into the next device as shown in Figure 3.
4) Based upon 54MHz clock (18.5ns). Output Setup Time = Clock Period - Output Delay Time
